摘要
利用USB-6009数据采集卡、LabVIEW编程工具和Mysql数据库设计出数据采集系统,由NextBoard信号源发出信号,利用LabVIEW的IDAQ模块完成双通道的数字系统采集。通过TCP模块完成信号传递,利用标示符来确定双通道信号的归属,数字信号采用PXI-6221数据采集卡通用I/O口作为信号源,服务端采集到信号并进行2ASK调制后再发送,客户端在接收到信号后进行解调,实现多信号传递功能。经测试系统可行,能够完成单机采集多机共享的功能。
A data acquisition system is designed by using USB-6009 data acquisition card,LabVIEW programming tool and Mysql database,in which the signals are emitted from NextBoard signal source and the dual channel digital system acquisition is completed by IDAQ module of LabVIEW.The signals are transmitted through TCP module,the attribution of the dual channel signals is determined by signer.The general I/O port of PXI-6221 data acquisition card is used as the signal source in the digital signals.the signals are collected by the server and 2ASK modulation is performed before sending,and the signals are demodulated by the client after receiving,so that the multi-signal transmission function is realized.Testing shows that the system is feasible and it can complete the function of single machine acquisition but multi machine sharing.
